SAP Fiori principal apps 1.0 for SAP ERP on Netweaver 7.5

Hello,

I'm trying to install SAP Fiori principal apps 1.0 for SAP ERP on my GW, specially app "Approve Purchase Orders" but when I go and look for the OData Service GBAPP_POAPPROVAL to activate it for my Alias, I can't find it. I have already activated the sicf service mm_po_apv.

Anybody knows why?

Landscape:

Central HUB Arquitecture

GW:

Backend:

ERP 6.0 EHP7 SPS08

Note:

I haven't installed component GBAPP002 600 on the back-end since it's my understanding I don't need to given my ERP version, but I think maybe that would be an issue later on, not when I'm tryng to look for the OdataService.
